What is the relationship between the area of a circle and its radius squared?

Answer 1

The area of a circle is defined by the equation A = πr^2

where π = pi (3.14...)

A = Area

r^2 = radius squared

So, the radius of a circle squared multiplied by pi equals the area.

Answer 2

Relationship between circle are and radius squa0red is

A(Area) = pi r^2(radius squared).

pi is the constant of proportionality for ALL circles . It has a value of 3.141592.....

However for elementary school work , pi = 3.14

NB Remember to other relationship with circles for circumference.

C = 2 pi r = pi d

Learn and commit to memory ;-

A = pi r^2 & C = 2 pi r
